Thousands of dams have been built around the world, but, the date of construction is associated with a history of failures and collapse, due to the high water levels, generating higher returns consequences disastrous for the environment and society, when dam fails released very large amounts of water threatened the lives of persons and property, it returns to the short time available for warning and evacuation. This paper provides an overview of the most important reasons for the collapse, with a study about possibility failure product from supposed breach in 16 Tishreen dam, caused by the flow of water over the top, where the predicted of breach that leading to collapse is done and determine its characteristics, namely: High, width, time required to development of the breach, the maximum flow out of it, and also generate flood maps that represent the limits of the spread of flood wave downstream, in addition tosuggest a simplified plan for the evacuation Results led to the flooded wave caused by the collapsehurtling loaded adischargeabout 54631 , causes a wall of water with 17 meters high moves through the downstream river with 14 m/sec speed, the wave spreadover 45.24 ,causing submerge for 7 villages the most important of it Stkhers and Rodo which are completely submerged, and 30 economical facility the most important of it industrial area that also completely submerged, the water depths ranged from 2 to 17 meter, which causing heavy casualtiesand damage about 30000 people, and more than 7000peopleare expected to die, unless the actual preparations of emergency plan.

The statistical Study of Jointsarround 16 Tishreen lake dame region in ALKabir ALShimali river basin showed the presence of several main groups of Joints with directions NE-SW _ NNE-SSW, NW-SE, E-W. - Group NE-SW: showed correspond to with the fau lt structures of same directions which are normal and reversal faults and distributing geographically 1n Lattakia Kallas fault zone. Also it showes correspond to with the axis of folds of same direction, thus explained as longitudinal joints within these folds - Group NW-SE: showed correspond to with faults structures of same direction. which are left and right lateral strike slip faults, Spread over the entire study area. and it may(diagonal)shear group within the folds of NE-SW axes. - Group E-W:correspond to with normal faults structures.
This study was conducted to determine the chemical and physical analysis of two important water sources in the coastal erea, namely: Northern Elkabeer river and Balloran Dam. The study took a year and a half starting from June ١٩٩٩. The temperatu re the cations and the anions were periodically determined in three sites selected along the river bed. Results showed, that there are a large variations in the concentrations of the studied elements, in both water sources. The same variations were also observed among the three defined sites of the same source according to the ruling climatic factors during the year. The increase in the concentrations of most of chemical elements in water source was observed when the temerature increased. These concentrations generally reach the highest value in the latest Summer and the beginning of Autumn. It was shown that the impact of the biogeochemical factors namely: rainfall and floods, the water drianing from soils and the effect of agricultural and in dustrial waste - water became clear . According to the international and Syrian standards of water chimical qualities, the water of Balloran Dam and ١٦ Tishreen Dam can be used for drinking and irrigation purposes. While water of the tow studied sites on the Elkabeer river can only be used for irrigoation.
This study aimed at determining the fish fauna composition in 16th of Tishreen Lake (Alkabeer Alshimali River). A total of 730 individual fishes were collected between April 2012 and March 2013 from five different sites along the lake /Alsafkoon, W ata-Alsheer, Alkerassat, Mazraet Alsheikh Deeb, and Alaqfaas area/. Our results showed the presence of only six main fish species belonging to three families (Tillapia zillii, Cyprinus carpio, Liza abu,Varicorhinus damascinus, Garra rufa and Garra lamta). The results also showed that Tilapia zillii was the most caught fish, and Wata-Alsheer was the richest site in the lake. These results showed a decrease in the number of fish species and their quantities compared to that in previous studies on the lake.
The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake water. The samples were taken at five sites along the lake for a period of one complete year. The indicators that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C. Measurement results were represented diagrammatically, and compared with the Syrian Specification Standards for portable Water. The lake was classed according to these Indices: Malays quality index, Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following: from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined. The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other locations.
Study of the general characteristics of Fractures in the central part of the AL-Kabir AL- Shimali river basin showed the presence of several main groups of Fractures with directions NE-SW _ NNESSW, NW-SE , E-W.and showed increased fracture rate in the northern and southern parts of the study area, and that the spacing between the Fractures close to the medium convergence (5-34) cm , also show a aperture ranged between (0.1-5.1) cm, where aperture width was increased in southwest of Lake 16 October near Lattakia- Kless fault .
